ASUS PRIME H310M-F R2.0 Does Not Power On

Please Find The Motherboard Image (With Board Number) Below:-


There is no +5VSB , and it is found that the G electrode voltage of PQ4002 (P-channel MOSFET) is more than 2V and does not conduct.

 

A 4120 ohm resistor   is used as the 5VSB_ATX pull-up resistor. I changed It to 85C and 75K and it still doesn't work.

Finally, I replaced it with PQ4002 . Working Fine 



Happy Repairing !!
